At a minimum one resistor only is to act as representative example for its measuring range. Additional requirement for such special high-resistance system this is max working voltage that must be able to cover 1000V nominal, up to a maximum of 4000V.</span></p><p style="margin:0;padding:0px;">&nbsp;</p><p style="margin:0;margin-bottom:6.0pt;"><strong style="font-size:11.0pt;font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;">The Solution</strong></p><p style="margin:0;margin-bottom:6.0pt;"><span style="font-size:11.0pt;font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;">The product specifications of the Powertron Thick Film GST 4020 Series resistors meet the application requirements of resistance value and working voltage.&nbsp; This outstanding product has even more to give: Precision level of 0.25% up to 2.6 G </span><em style="font-size:10.0pt;font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;">Ω </em><span style="font-size:11.0pt;font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;">and a remarkable TCR specification.</span></p><p style="margin:0;margin-bottom:6.0pt;"><span style="font-size:11.0pt;font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;"><span style="font-size:11.0pt;font-family:&#39;Calibri&#39;,&#39;sans-serif&#39;;"><a class="jive-link-external-small" href="http://www.vishaypg.com/doc?63630" rel="nofollow ugc noopener" target="_blank">http://www.vishaypg.com/doc?63630</a></span> </span></p><p style="margin:0;padding:0px;margin-bottom:6.0pt;">&nbsp;</p> <div class="migration-injected-attachments"><div style="font-weight:bold;margin:15px 0 5px 0;">Attachments:</div><div></div><table style="border:0;"><tbody><tr><td width="160"><span class="_se_attachment" id="attid_https://www.element14.com/community/api/core/v3/attachments/234909"><a href="https://community.element14.com/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-21/63630_5F00_Final_5F00_170326.pdf">community.element14.com/.../63630_5F00_Final_5F00_170326.pdf</a></span></td><td><span style="font-size:80%;">63630_Final_170326.pdf</span></td></tr></tbody></table></div><div style="clear:both;"></div> <div style="font-size: 90%;">Tags: test equipment, high-voltage, high-power, calibration</div>
